The disappearance of Ettore Majorana: an analytic examination

The many recent researches into the mysterious disappearance of Ettore Majorana, one of the greatest minds of theoretical physics in the twentieth century, are summarised and discussed in some detail. The fate of the Italian scientist is argued to be intimately related to the final months of his life in Naples, from where he decided to disappear in Match 1938. This analysis of accurate and detailed investigations performed in the last few years, together with facts already known, reveals a fascinating and intriguing picture, which was previously unexpected. New light on the disappearance of Majorana, a mystery that has lasted for more than 70 years, then emerges.
